Fixes #1970

This PR add the logic that set the minimum played episode count required to allow the user to rate a podcast. The value could be 1 or 2 depending bby the number of episodes a podcast can have. If the podcast has only 1 episode, than the minimum value will be 1. If the podcast has more than 1 episode, than the minimum value is 2.
